主 题：low carbon steel bainite phase transformations chromium microstructure mechanical properties
摘 要：To develop low-cost low carbon bainitic steel,Mo-bearing and Cr-bearing steels were melted in a vacuum induction furnace and were researched by thermal simulation and hot rolling at the *** the cooling rate increases from 0.2 to 50°C/s,the transformation temperatures of two steels lie between 650 and 400°C,and the final microstructures of them change from quasi-polygonal ferrite and granular bainite to lath *** with cooling in air or by interrupted cooling,Mo-bearing and Cr-bearing steel plates cooled by sprayed water boast higher strength and superior toughness,for large-size islands are responsible for the poor mechanical *** to Mo,Cr is effective to isolate the bainitic reaction in low carbon steel,and the bainitic microstructure can also be obtained in Cr-bearing steel cooled at a wide range of cooling rate.
